Just to clarify, the X5 is NOT regulated. Its merely resistored down. That means that the brightness at 20 hrs will be pathetic and you'll most likely want to change the batteries at 1/2 that or maybe even 1/4 of that if you value quality light. The light is a bit outdated and Inova knows that. As such, Inova has updated the light, which is sold as the Inova X0. This contains a 1w luxeon.
Runtime plot for the X0:

For reference, here's a runtime plot of the X5:

If you have only a passing interest in quality flashlights, pass up the LED conversions for the mag2AA and just get a streamlight jr. luxeon.
